Speed, size, and strength are thought to be important factors in football performance. The article "Physical and Performance Cha

racteristics of NCAA Division I Football Players" (Research Quarterly for Exercise and Sport [1990]: 395–401) reported on physical characteristics of Division I starting football players in the 1988 football season. Information for teams ranked in the top 20 was easily obtained, and it was reported that the mean weight of starters on top-20 teams was 105 kg. A random sample of 33 starting players (various positions were represented) from Division I teams that were not ranked in the top 20 resulted in a sample mean weight of 103.3 kg and a sample standard deviation of 16.3 kg. Is there sufficient evidence to conclude that the mean weight for non-top-20 starters is less than 105, the known value for top-20 teams?

Answer:

no

Explanation:

H0: mean of sample=105

Ha: mean of sampe≠ 105

t-statistic= (population mean-sample mean)/(standard deviation/√sample size)

t-statistic= (105-103.3)/(16.3/√33)

t-statistic= 0.5991

degress of freedom= 32

for alpha 0.05, p-value from t-distributino table is 1.697

since t-statistic is less than the p-value, null hypothesis is accepted.

There is no sufficient evidence to conclude that the mean weight for non-top-20 starters is less than 105 the known value for top-20 teams

If you compute the price elasticity of demand using a quantity of tickets from 1 to 8 and using a quantity of tickets from 1,000
LenKa [72]

Answer:

The correct answer is option B.

Explanation:

The value of price elasticity of demand will be the same if the quantity of tickets changes from 1 to 8 and 1,000 to 8,000. The price elasticity is calculated on the basis of proportionate change in quantity demanded.

The proportionate change in quantity demanded is the same in both cases. So, the price elasticity of demand will also be the same.

Suppose you are running a carnival. You are selling hamburgers and sodas. A hamburger is $1.75 and a soda is .75. You expect to
Sunny_sXe [5.5K]

Answer:

<em>Hamburgers = 27</em>

<em>Sodas = 93</em>

Explanation:

Let        x = Hamburgers

             y= Sodas

Now form a system of equation aX + bY = C

where

a= 1.75 = coefficient of variable X

b= 0.75 = coefficient of variable Y

C= 117.50

Put these values in above equation

           1.75x + 0.75y = 117.50 . . . . . (1)

Since I sold total of 120 hamburgers and sodas, we can write

            x + y = 120  . . . . . (2)

or          y = 120 - x          ....... put this value in eq.1

           1.75x + 0.75( 120 - x ) = 117.50

           1.75x + 90 - 0.75x = 117.50

            90 + x = 117.50

             x = 117.50 - 90

             x = 27     .......... put this in equation 2

     

          x + y = 120

          27 + y = 120

          y = 120 - 27

           y = 93

allochka39001 [22]

Answer:

$2,46500

Explanation:

Self-employment Earnings are profits made from carrying on a "trade or business" as a sole proprietor, an independent contractor, or some form of partnership. For a trade or business, to be considered self employment, does not have to be profitable, and it shouldn't be a full time thing but profit must be your motive.

To calculate your self employment income Subtract ordinary and necessary trade or business expenses from the gross income you derived from your trade or business.

Note that, the amount subject to self-employment tax is 92.35% of your net earnings.

Remember you pay income tax on your profits only, not your total income. Subtract your business expenses from your total income. This is the amount you will pay income tax on.

For Karlie

HI taxable Self employment earnings = $85,000

HI Self employment tax = ($85,000 × 0.29)

= $24650

Hence the portion of her earnings subjected to two parts of security tax is #2,46500.
